IMPROVEMENT IN MACHINES FOR WEAVING CORDS 0R COVERINGS AROUND CORDS.

Specification forming part of Letters Patent No. 43.937, dated August 23, 18764.

.T0 all whom it may concern:

Be it known that we, FLORENCE VEERKAMP and FRANCIS LEOPOLD, both of Philadelphia, Pennsylvania, have invented an Improved Oord-Weaving Machine; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being` had to the accompanying drawings, and t0 the letters of reference marked thereon.

Our invention consists of novel mechanism, fully described hereinafter, for weaving cords and for forming woven fabrics around cords.

In order to enable ohers'skilled in the art to make and use our invention, we will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specification, Figure l is a vertical section of our improved machine for weaving cords, and Fig. 2 a plan view.

A is an annular plate, which is supported by uprights B, secured to the base-plate C, and which surrounds another plate, A', there being between the two plates an annular opening, a, with which communicate a series of straight openings, b, made-in both plates and arranged to Aradiate from the center of the same.

Through the centers of the plates A and C passes a vertical tube, D, open at both ends, and around thatportion of the tube between the plates turns another tube or sleeve, F, to the upper end of which, beneath the plate A, is attached a disk, G, in such a manner that the latter is eccentric with the sleeve. In the upper face of the disk are two annular grooves, c and c', arranged eccentrically and so that one may communicate with the other at the point x, which is directly below the annular openin g a.

In each of the radial openings b a plate, d, fits snugly, but so as to slide freely to and fro, and to each of these plates is secured a rod, H, carrying a spool or bobbin, I, containing thread w, which may be termed warp-thread.7

On the underside of each plate d is a pin, to which is hung a swivel, t', the latter projecting into one of the grooves in the disk G. To this disk is attached a rod, J, which projects upward through the annular opening a in the plate A, and carries a bobbin, l. The thread y from the latter passes through an eye inthe top of the rod, and may be termed the wett-thread. Beneath the disk G, and secured to the sleeve F, is a grooved pulley, K, round which passes a cord from any adjacent driving-pulley.

Before proceeding to weave the threads from thev bobbins together into the form of a cord the plates d are so arranged that lthe swivels of no two adjacent plates shall be in the same groove of the disk, no two adjacent bobbins, therefore, being on the same side of the annular opening a. As the disk revolves, each swivel is so acted on by the sides of the groove into which it projects that it is transferred from one groove into the other at every revolution of the disk. A reciprocating m0- tion along the radial openingsb and across the annular opening a is thus imparted to the A plates d and to the bobbins on the same, while the bobbin I is carried round continuously in a path coinciding with the said opening c.

When it is desired to weave the threads on the bobbins round a central cord, X, the 1atter is passed upward through the tube D and s'ecuredvto a reel, round which it is wound as the work progresses. The ends of the threads w and y are then attached to the cord a short distance above the end of the tube D, and a rotary motion in the direction of its arrow is given to the disk G. As the disk revolves, the bobbin l is carried across the paths ot' the bobbins I, which are Inoved back and forth in the manner above described. Thus the thread of the bobbin I is interwoven with the threads of the bobbins .I precisely as the weft-thread is interwoven with the warpthreads iu an ordinary power-loom, and the cord X is thus surrounded with a woven fabric.

It will be seen that a machine of the above character can be constructed at a slight cost, and that it can be driven at a high speed with but little friction or wear. When a small cord is required, the central cord, X, may be dis pensed with, and variety may be given to the work by so adjusting the plates d that two or more adjacent bobbins shall move together in the same direction at the same time.

We claim as our invention and desire to secure by Letters Patentl. A series of bobbins so arranged as to move radially from and toward a given oenter, in combination with a bobbin which moves continuously around the said center and across In testimony whereof we have signed our the paths of the other bobbins, substantial] y names to this specification in the presence of as and for the purpose set forth.

2. The lplates A and A with the openings two subscribing witnesses. d, and b, when constructed and arranged for the reception and operation of the plates d and rod J, substantially as specied.

3. The disk G, with its grooves c and c and rod J, when arranged and operating subst-aw tially as described, for the purpose specified.
